Chase mobile app:

The first generation iPad Air, iPad mini2 and mini3 can only be updated to iOS 12.5.4.

Apple ended major update support for these models of iPad in September 2019 - although they since continue to receive “point” security updates - the most recent being released just a few days go. These devices cannot be updated to iPadOS 13 (or any later major versions of iPadOS) as the internal hardware does not meet the minimum technical requirements (CPU and RAM) for newer versions of iOS/iPadOS.

Some App developers have dropped support for iOS versions preceding iOS 13.x for technical reasons (often because APIs or software libraries upon which they rely have been updated in the new version of iPadOS, making their App incompatible with earlier versions). 

Whilst many App titles remain compatible with your iPad, if you want or need to access to Apps requiring the most recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model that supports iPadOS14.

Sorry, I appreciate that this may not be what you were hoping to learn. As for your inability to install your Chase Banking App, are you able to access your account using your Bank’s we portal? Whilst you may not be able to install the App (which is very likely just a web front-end), a browser may be all that you need.

I hope this information provides helpful clarity as to your available options - and the limitations of your existing iPad.

Receiving error message that the app will only work with the updated IOS 13.0 on the iPad. IPad doesn’t have an update beyond 12.5.4.

Then will either need to access your account through safari on your current ipad, or upgrade to a newer ipad so you an access the app.
